Application filed September 25, 1924. Serial No. 739,854.

This invention relates to shingles and more particularly to flexible shingles which are cut from strips of suitable material. One object of the invention is to provide shingles which can be laid on the roof in such a manner as to present a pleasing a pearance. Another object is to so form t e shingles and lay them on the roof as to lock down the exposed edges of the shingles so that they will l" not turn upwardly because of warping, or bending by winds or otherwise. Another object is to provide shingles so formed that they can be laid on the roof of single thickness and at the same time form a dependable l5 and waterproof covering. Other objects of the yinvention will be apparent fromthe accompanying drawings and the following description thereof.

Of the drawings Fig. 1 is a plan view of a strip of shingle material indicating how the individual shingles are cut from the strip;

Fig. 2 is a plan view of the assembled shingles on a roof; and Fig. 3 is a plan view of an enlarged unit shingle, showing the details thereof. While one feature of my invention is to provide a shingle that can be cut from strips without waste of material,l as is indicated by Figs. 3 and 1, yet a further purpose ofthe invention is to provide a unit shingle which in itself contains no waste material and is en-` tirely sufficient` for the purpose. In the formation of shingles from strips, while inmany cases the strips may be used up apparently without waste material, yet the shingles are so formed as to have unnecessary material at certain portions and to be more or less deficient' in material at other portions; the main purpose apparently being to prevent cutting from the strips the small pieces which are not of use. But in this invention I have provided for the use of all of the material of the strip and have so formed the shingle that it is just the right shape for the purpose without any surplus or deficiency in material. Also in carrying out the inventionr the object has been to provide for roof coverings of single thickness of ma,

terial, except where the edges of the material lap in order to prevent leakage f theoovering. In thls manner the expense for the rooi` covering, so far as material is concerned, is reduced to a minimum.

Furthermore, I so form the shingles that the assembling of the shingles on the roof can be materially expedited because of theparticular shape of the individual units. A special feature of the invention, however, is to provide a roof that will be pleasing to thc eye but which has not the ordinary shapes of figures on roofs. and providing for more or less variations in the particular shape of the figure without varying from the scope of my invention, such variations being obvious to any ordinary workman.- The shingles also give a distinctive feature to the roof. This feature comprises a. straight horizontal line produced by the rows of the lower edges of the assembled shingles, these edges forming an unbroken line from one end of the roof to the other, the line being ordinarily horizontal but not necessarily so. Furthermore, the shingles are attached to the roof by nails or otherwise in a simple manner, and with a minimum of nails, and so as'to prevent any tendency of the shingles becoming elevated above the plane of the general roof covering.

Each of the individual shingles 10 has a lug 11 projecting from one side of what is the lower edge of the shingle when laid on the roof and a lug or corner 12 projecting from the opposite side of the shingle.' In laying the shingles theedge 13 on the side of the shingle which carries the lug 11 is lapped on to the edge 14 of the adjacent shingle; and the lug 11 is slipped under the lower end ofthe same edge of this adjacent shingle. As a consequence the two shingles lap sufficiently to prevent leakage and at the same time both shingles are locked down by the other so that the edges of neither can bow' upwardly without raising the other shingle. And the shingles are nailed at the points 15 and 16 `so that at each lap there is a nail and one at the opposite corner of each of the shingles. This prevents any possibility of the 4 edges of the shingles bending upwardly and at the same time each nail puncture is covered by the shingles. The nail 16 is covered by the upper row of shingles lapping thereon and the nail 15 is covered by the adjacent right hand shingles lapping thereon. It will thus be seen that a roof covering in this manner providesfor ample meansfor protecting the roof from the weather and prevents any tendency of the edges' of the shingles rising above the general plane of the roof.

, In order to reducethe tendency of the rain to be driven between the adjacent edges 13 and 14 of the shingles I incline these edges as indicated so that gravity tends to force the rain downwardly and away the edges; and this, at the Vsaine time, gives a pleasing appearance to the roof, and also an o portunity of varyingA the design of the roof y varying the inclination of these edges to suit the particulartaste of theowner, or the type. of architecture, or the like. Arid, laying the shingles as indicated, each row has at its lower and upper edges, a well defined line, formed bythe exposed edges of v sha e with the lug. And to form a morev per ect union between the edges and to simplify the laying of the shingles I provide a slit or slot 18 into which the upper edge of the lug 11 passes as the lug is slipped under the shingle. In this manner the corner 19 assists in binding the lug in place so that thereis less danger of its being forcedout by'wind or otherwise. In laying the shingles it is necessary only for the workman to slip the lug into place and then rotate the shingler around the lug until the upper or the lower edge is in line with the corresponding edge of the adjacent shingle. He then drives the ltwo nails in the shingle in the points indicated and the laying of that unit is complated. However if desired, the shingle may be laid as, indicated in Fig. 2, so that the corner 20 of one Yshingle strikes against the edge 21 of the adjacent shingle and thus an additional guide is provided for assisting in placing the shingle. Y j

I claim as my invention:

1. A shingle having the general shape of a .parallelogram' with oblique angles; the said parallelogram having a rectangularlyv shaped portion projecting from one of its sides, and a lug projecting from one o the opposite corners.

2. A shingle having the general shape of a parallelogram with oblique angles; the said parallelogram having a rectangularlyshaped portion projecting from one of itsA sides, a lug projecting from one of the opposite corners; and a-,recess formed in the other opposite corner.

3. A shingle having in general the shape of an oblique-angled parallelogram, said shingle having a lug projectin from one of the obtuse angles and a portion projecting outwardly from the side of the shingle opposite the lug.

4, A shingle composed of flexible composition material. the central portion of which is diamond-shaped, the said central portion having a piece projecting from one side, said piece being shaped asa rectangular parallelogram. with two of its corners registering with the two adjacent corners oi the body of the shingle, and another piece projecting from the opposite side of the said central portion. said latter projection being substantially the same length as said side, but withl its corners spaced from the adjacent corners of the side.

5. A roof covering comprising a plurality of individual shingles, each of said shingles having a lug projecting from one lower corner and a recess formed in the other lower corner: the said shin les being laid in .rows with the lug of each s ingle projecting under one edge of the recess of the adjacent shingle: and a slit formed in one of the edges of said recess into which a portion of the lug of the adjacent shingle projects.

6. A shingle composed of flexible material and having the general shape of a parallelogram, a lug projecting from one corner of said shingle, and-said shingle having a recess formed in one of the adjacent corners of said shingle, and a slit formed in one edge of said recess.

In testimony whereof, I'hereunto set my hand.
